2013-S Mount Rushmore, Silver Proof

San Francisco struck 467,961 pieces of the 2013-S Mount Rushmore silver proof to close the year's five-design ATB slate, the figure matching U.S. Mint product-sales records for the 2013 Silver Proof Set. The coin lands in the stable 460-thousand-piece silver-proof band the program held through 2015 before drifting lower in 2016 and 2017. Don Everhart's reverse depicts a sculptor on suspended scaffolding finishing the Thomas Jefferson face during the monument's mid-1930s carving phase, a construction-era moment rather than the completed tableau most readers expect. The composition pulls focus to the working figure against the still-rough granite of the partially-carved face. The 90% silver composition (.1808 troy ounces of pure silver inside a 6.25-gram quarter at 24.26 millimeters with a reeded edge) is the pre-2019 standard ATB silver-proof alloy.

Authentication on the coin anchors on weight and edge appearance. A calibrated jeweler's scale resolves the 6.25-gram silver reading against the 5.67-gram clad-proof reading without ambiguity, and the edge reads as a uniform silver-gray reeded band with no copper-core sandwich visible. PCGS and NGC apply a "Silver" attribution to the slab label on top of the numeric grade and Cameo or Deep Cameo contrast designation. Cameo (CAM) is moderate frosted-device contrast; Deep Cameo (DCAM) is the higher-contrast tier and the default outcome on the issue rather than an upgrade step. Grade distribution clusters at PR69-DCAM and PR70-DCAM with population counts in the thousands at the top tier. The design-specific diagnostic is the scaffolding-rope and pulley detail and the granular texture of the unfinished granite, both fine-relief features that flatten under weak press pressure.

The coin trades in the modern silver-proof band with pricing that follows silver spot for most of its movement and a modest set-completion premium on top. PR69-DCAM examples move for a small step over melt plus slab cost, and PR70-DCAM examples in NGC or PCGS holders carry a modest tier above that. The 467,961 silver-proof print run is roughly 38 percent of the 1.23 million 2013 clad-proof figure for the same design, which gives the silver version a structural scarcity edge against the clad sibling. Mount Rushmore is the most visually recognizable subject in the 2013 slate and draws South Dakota regional and presidential-history crossover collectors, though that recognition has not separated the issue from its four sister designs in pricing.
